Buying Guide: Key Purchase Considerations
Bed length and width compatibility are critical: most systems here target beds up to 24′ long and widths around 110″. Verify your truck’s exact measurements before choosing a model. Consider arm material and finish: aluminum systems offer corrosion resistance and lighter weight than steel, which can improve efficiency and reduce wear on mounting points.
Motor power and gearing influence cycle speed and load-taming ability. A 50:1 gear ratio is common and balances torque with RPM. Check the motor’s voltage requirements (12V is typical for light to medium-duty applications) and ensure your electrical system can handle the current draw safely.
Accessory inclusions matter: some kits come with tarps, switches, and battery cables, while others are sold as arms-only or require separate purchases. A robust rotary switch and durable cabling reduce installation time and potential wiring issues. Tank-like bushings, stainless sleeves, and reliable pivots extend the system’s lifespan in dirty dump-yard conditions.
Warranty and support are important for field equipment. Look for at least a one-year warranty on aluminum components and a warranty on the motor assembly. Original equipment compatibility with brands like Roll Rite or Donovan can ease future replacements or upgrades if you already own components from those lines.
Installation effort varies: some systems are modular with simple bolt-on designs, while others require more cutting or drilling. If you lack shop tools, prioritize kits with simpler cross-tube adjustments and clear instructions. Finally, consider whether a full system (motor, tarp, switch, and cables) or an arms-only upgrade best fits your needs.
